From Latinquaerere, present active infinitive of quaerō(“seek, look for, desire”). In the 19th century, the older form of the simple perfect, cerșii, from Latin quaesīvī, was replaced by cerui by analogy and the old past participle, cerșit, from Latin quaesītus, was replaced by cerut. The r in these obsolete words were themselves a relatively modern addition through analogy with the original word. [1]
